Im looking at starting a undead team and I would like to have all the star player models available to me just incase I need to get them with inducements, The problem is I can only find Ramtut III and Hack Enslash

You kindof can't. GW doesn't support BB anymore, so haven't made the models.

So you get to improvise! Anything with a knife for Sinnedbad. Altho, in my experience, he is as effective as a blind retarded child armed with a 3 day old herring, so perhaps a model holding a fish would do?

Are you suggesting that blind retarded children (who do exist - I'm simply describing the condition that certain people in this world exist in) would be effective with a wet fish? If so, I apologise for downplaying their lethal abilities with piscine hand to hand combat.

There are unnofficially adopted models that most people use for the Undead Stars. Obviously this list isn't definitive and by no means complete, but what I've seen people use are...

Sinnedbad
Any undead BB model converted to have a blade for an arm, or this model by Impact Miniatures.

Setekh
There's nothing official in the fluff as to who/what Setekh actually is, so again you can use pretty much anything that looks ST4 to represent him? I like the Impact Anubis models, drop me a PM if you're in the UK as I may have one spare you could buy?

J Earlice
The Heresy Deathball Ghoul is great for him. While you're at it, the rest of their Ghoulrange makes great conversions for BB Ghouls instead of the crazy fat GW models...

As for the other three (Count, Ramtut and Hack), these are all available as GW minis. I have plenty of alternatives for them as well if you want to look past the standard GW range, just ask?
